lMPROVEMENT IN AXLES AND REACH ES FORVEHICL ES.

Specification forming part of Letters Patent No, 36,914, dated November11, 1832.

To aZZ whom it may concern:

Be it known that we, SYLVEsTER O. Post, of the city of Chicago, in thecounty of, Cook, State of Illinois, and EUGENE J. Posr, of Vienna, inthe county of Warren, State of New Jersey, have invented new and usefulIm provements in the Application of Material and in the Construction ofAxles and Beaches for Vehicles; and we do hereby declare that thefollowing is a full, clear, and exact de' scription of the same,reference being had to accompanying drawings, making a part of thisspecification, in which Figure 1 shows a side view of an axle fortransportation. Fig. 2shows the underside of a single corrugated axle.Fig. 3 is a top View of a very strong axle for light vehicles. Fig. 4shows an axle and section of a reach. for light-draft vehicles. Fig. 5is an end view or section across Fig. 1. Fig. 6 is an end view orsection across Fig. 2. Fig. 7 is an end view or section across Fig. 3.Fig. 8 is an end view or section across Fig. 4.

Our invention consists in the construction and application of corrugatedsheet iron or steel to be used for axles and stretchers or perches forvehicles; also the manner of securing the arms to the same.

To enable others skilled in the art to make and use our invention, wewill proceed to de scribe it more fully, referring to the drawings, andto the letters of reference marked thereon.

In order to get the greatest amount of strength and stifi'ness with theleast weight of material, we make the bar or bolster A A, which connectsthe axle-arms a a a or together, of sheet metal, iron, or steel, thesame being bent or corrugated in such a form, and put up and securedtogether in such a manner, as to support the greatest weight and strainpossible in proportion to the weight of the axle.

The axle-arms, if desired, may be made of hard tough wood bb having askein of iron, 0 a, let into them in the usual way, the same beingsecured to the corrugated bow A by bolts or rivets e, as seen at theleft-hand end of Fig. 2; or they may be made of cast malleable iron, orwrought iron or steel, so swaged and shaped as to form tenonsff, whichfit in the openings at d d in the ends of the bars A left by the curvingand shaping of the metalused for the purpose of axles. The arms a a thusfitted may be firmly secured in their places by bolts or rivets i 17 z zt put through the whole.

The stretcher or perch B, or any of the other parts of the running-gearof land-vehicles, maybe made of sheet corrugated metal, so constructedand shaped as to possess six times the strength and tenacity of anymetal of the same weight in any other form. Thus it will readily be seenthat by the application of our invention armywagons, omnibuses, andother vehicles for heavy transportation, as well ascoaches,buggy-wagons,.and every description of pleasurecarriages, can be made atleast one-third lighter, and possess more strength, elasticity, andconsequently more durability, than any that have been before known orused.

Corrugated metal for all purposes where great strength and a certainamount of yielding is necessary has been found to possess the requisitequalities, and its adaptation to various purposes has been rightfullysecured to those who have discovered and applied it, and there is not,perhaps, another place Where its utility can be better tested than whenapplied to the running-gear of such vehicles as are required for heavytransportation over the rough and mountainous roads in this country.

' Having thus described our invention, what we claim as new, and desireto secure by Letters Patent, is-

The application of corrugated sheet metal to bars or bolsters forwagon-axles and the mode of securing the arms to the same, in the mannerdescribed, and for the purposes herein specified.
